Hey all. I've had plenty of experience with SLP keys and OEMBIOS files in XP, on XP I'd use an OEM key, then use the OEMBIOS file changer, then use the Genuine Windows Key Changer tool thing to change the key to the one of the system. This is my first time with Windows 7 and I don't have a clue. The system in question is Home Premium X64 on a friend's laptop which had a failed HDD. 1) I assume it won't just activate with the key on the bottom, just as it was with XP? 2) I downloaded an Acer Home Premium OEM sources package from a sticky thread on this forum. Am I right in thinking the $oem$ folder just drops in the root of the setup disk? Do I have to add anything to make it run the .bat files responsible for activation? If I've got it all wrong, how do I go about activating Windows using the key on the bottom? Cheers!
